SILENCER.

Appleman sied .April 4, 192e.

This invention relates to a silencer for association more particularly with a supply tank of an ordinary toilet flush box for lthe purpose of stopping the noise of inflowing water through the ball cock valve into the supply tank.

The noise referred to is that noise or hissing and squealing sound caused by the swift inrush of water against the ball cock lo inside the tank, especially when the ball cock is closing.

It is therefore one oi the principal objects ol the present invention to provide a silencer that terms a part of the supply pipe Jror the a flush tank which will eliminate these objectionable noises, yet permit the flow of the water through the tank in a positive manner.

One of the ilnportant objects of the present invention is to provide a silencer of the 2o above mentioned character which is of such construction as to permit the parts comprising the same to be readily and easily assembled and disassembled for cleaning purposes, the same being further simple in conf struction, inexpensive, strong and durable, and further well adapted to the purpose for which it is designed.

Other objects of the invention will become apparent as the nature of the invention proceeds and when taken in connection with the accompanying drawing.

In the accompanying drawing, forming a part ot this application and in which like numerals designate like parts throughout the several views:

Figure 1 is a. side elevation of the silencer embodying my invention, showing the manner in which thel same is associated with the supply tank of an ordinary toilet flush box, and a portion of the water supply pipe, and

Figure 2 is a vertical sectional view through the silencer embodying my invention.

In the drawing, wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numeral 1 designates generally'the silencer embodying my invention, the same comprising lower and upper pipe sections 2 and 3 respectively and the intermediate section 4, each of said sections being preferably constructed of brass material.

The lower pipe section 2 is formed at its lower end with an externally threaded neck 55' 5, for threaded engagement into the elbow Serial No. 267,295.

6 at one end thereof, the other end of said elbow being threaded onto the water supply pipe '7 that leads from any suitable source of supply. The lower portion of the section 2 is formed with the tool engaging face S, to facilitate turning movement of said section.

An externally threaded neck 9 is formed on the upper end of the lowermost section 2, and the upper end ot' the neck 9 is reduced and externally threaded as illustrated at 10 for receiving an internally band 11, the upper edge of which is formed with an inwardly directed flange.

A screen 12 is arranged in the upper portion of the flanged band l1 and suitable washers are disposed on opposite sides of the screen, one washer being in engagement with the upper edge of the reduced portion 10, while the other washer is in engagement 75 with the inner face oi the inwardlydirected flange formed on the upper edge of the band.

As is clearly shown in the drawing, with reference more particularly to Figure 2, the bore of the threaded neck portions 5 and 9 as well as the major or body portion of the lower section 2 are of the same diameter.

The intermediate section 4 is internally threaded at its lower end for threaded en- 85 gagement upon the externally threaded upper neck 9 and a washer 13 encircles the neck 9 for disposition between the lower edge of the intermediate section 4 and the shoulder formed at the juncture of the body portion of the section with the upper neck 9.

An externally threaded neck 14 is formed on the upper end of the intermediate section 4 and the bore of the neck 14 is smaller than the bore of the major portion of the intermediate section as more clearly disclosed in Figure 2. The upper end of the neck portion 14 is reduced and externally threaded and this portion is denoted by the numeral 15.

A filter or screen carrying unit designated generally by the unit 16 and which is identical in construction with the screen unit secured on the reduced upper end l() of the neck portion 9 formed on the upper portion lof of the lower section 2 is detachably secured on the threaded reduced portion 15 of the neck 14.

The upper section 3 is internally threaded, at its lower end for engagement with the externally threaded neck 14, formed on the upper end oi' the intermediate section 4 and a washer 17 encircles the neck portion 1 Jfor disposition between the lower edgeof the upper section 8 and the shoulder formed at the juncture of the intermediate section 4L with its neck 14.

rl`he upper end of the uppermost section 3 is formed with the externally threaded neck 18 that is threaded into the lower end of a coupling sleeve 20. A spud 21 extends from the bottom of the supply tank A and a sleeveor nipple 22 is connected at its upper end in the spud by means of the coupling 23. ylhe lower end of the nipple 22 is threaded into the upper end of the coupling sleeve 20. In this manner the silencer will communicate with the ball cock structure (not shown) and arranged in the supply tank in the manner well known in the art.

The uppermost section 3 of the silencer is 'formed with a tool engaging portion 19 and 1t is of course understood that a washer is disposed over the neck 18 for position be r' tween the shoulder formed at the juncture of the neck 1S with the body portion of the uppermost section 3 and the coupling sleeve 2O to prevent leakage.

Thus, the silencer' forms a part of the supply pipe and the water will flow upwardly through the silencer into the iiush tank in such a manner as to eliminate objectionable noises that usually occur where the water rushes into the flush tank with the connections now generally in use.

Although l have shown the silencer as being associated with the supply tank of an ordinary toilet flush boX, the invention may be equally as well used on water faucets for the same purpose.

The simplicity of my invention enables the parts to be readily and easily assembled and disassembled for cleaning purposes and should one of the pipe sections become worn, it may be replaced with a new one, without necessitating the entire replacement of the silencer.

l/Vhile .I have shown the preferred embodiment of my invention, it is to be understood that minor changes in the size, shape and arrangement of parts may be resorted to without departing from the spirit of the invention and the scope of the appended claim. Y

Having thus described my invention, what l claim as new is:

A silencer of the class described comprising upper and lower pipe sections, and an intermediate pipe section, an externally threaded neck formed on the upper end of the lower and intermediate sections respectively, the lower end of the intermediate section being threaded on the neck of the lower section, the lower end of the upper section being threaded on the neck associated with the upper end of the intermediate section, a neck formed on the lower end of the lower section, an additional neck formed on the upper end of the upper section, the upper end of eachot the necks formed on the upper ends of the lower and intermediate sections respectively being reduced, a screen unit detachably mounted on the reduced upper ends of the lower and intermediate secsection being Yof the same diameter throughout the entire length of said pipe section, the bore of the neck associated with the up* per end of the upper and intermediate sections being smaller than the bore of said sections.

In testimony whereof I aiix my signature. i
